I'm not sure, how tagging in AAC is different from MP3, so that may be the problem, but once you've figured out the needed fields, it should be trivial to wrap a script around it._________________++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.>+.>.

Mh, I'd just grab the metadata needed, decode via faad, pipe that to lame and re-insert the data with some tagger - should be quite easy and I couldn't find a working direct solution either._________________++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.>+.>.
